I have this blackjack layout and every panel and textfield already on the box except I don't know how to properly alligned them. I've been reading about layout manager but I get confused. I hope anybody can help me.

Explore Layout Managers. JPanel uses FlowLayout by default, so you'll see that as you resize the GUI you've built while it's being displayed, the components will move around to fit within the shape of the container but maintain the same order. You may want to use different layout managers in multiple containers to get the look you're going for.
